[RFA 07/13] Remove unused declaration from py-prettyprint.c

[Tom Tromey <tom@tromey.com>]

This removes an unused declaration from py-prettyprint.c, but leaves
the call to value_contents_for_printing, as it may throw.

2018-07-12  Tom Tromey  <tom@tromey.com>

	* python/py-prettyprint.c (gdbpy_apply_val_pretty_printer): Call
	value_contents_for_printing for effect.
